The fishing nets pulled out by fishermen operating in Osaka Bay, Japan, "contained more garbage than fish", which illustrates the serious pollution of the ocean by humans.

① The destructive effect of humans on the natural environment , mainly manifested in three aspects:

② The "three wastes" are arbitrarily discharged. Every year, the total amount of harmful waste gas in the air around the world is more than 600 million tons, the amount of waste water is more than 420 billion tons, and the amount of waste residue is also high. It’s amazing. Since 1873, more than 10,000 people in Western society have died from air pollution, and countless people have become sick. Water pollution is even more serious. The major water bodies in the world are affected by the “three wastes” to varying degrees. Pollution, and even highly toxic chemicals such as PCBs have been detected in penguins in Antarctica. The huge pollution has caused a large number of marine life, and many fish and shellfish are on the verge of extinction. Osaka Bay in Japan was once rich in fish and shrimp. Famously, the fishermen working here now haul out more garbage than fish!

③Excessive concentration of industry and cities is an important cause of pollution and environmental damage. For example, in Japan, 70% of factories. Squeezed into 2% of the land, 1% of the land is home to 25% of the population; the eastern United States has more than 120,000 square kilometers of land, bringing together 70% of the country’s manufacturing industry and nearly half of the population, making these areas a The world's famous "polluted areas". Environmental pollution problems such as garbage, sewage, and exhaust gas caused by excessive concentration of urban population are also particularly important.

④ The unreasonable development and utilization of natural resources has also seriously accelerated the geographical development. Environmental deterioration. For example, the "Black Storm" occurred in the United States and Russia because of the destruction of forests and grasslands, which caused strong winds, flying dust, and darkness. Mexico City sank 9 meters in 80 years because of excessive extraction. Caused by groundwater.

⑤ There are many ways to damage the environment, but the geographical environment, as the basis for human survival, has its own principles, and anyone who violates them will be punished by nature.
